Many companies sell identity theft services. These services may be able to help you detect identity theft quicker than you could yourself so that you can take action to prevent further damage. And some help victims resolve problems caused by identity theft. But the claims for identity theft services are sometimes exaggerated or misleading, and may not be easy to tell from their websites and advertising exactly how they work, how much they cost, or what protection or assistance they really offer. If you are considering identity theft services, look for companies that follow good practices.
